Analysis of the current state of the bitter-salty lake Ebeity located in the south of the Omsk region

The paper analyzes and identifies the main problems of Lake Ebeity located within the West Siberian Lowland in the endorheic territory of the Irtysh-Ishim interfluve. It was found that changes in the conditions for the formation of surface runoff under the influence of technogenic factors led to a decrease in the lake level with the exposure of significant areas of salt marsh areas. It was revealed that due to the increase in air temperature over the past decades, the environmental situation in the basin of Lake Ebeity is deteriorating every year and may reach a critical state, when further rehabilitation will be problematic or even impossible. The main reasons for the decrease in runoff from the catchment area are considered. Based on the analysis of hydrological and climatic conditions, runoff from the surface of the catchment area was calculated, and options for measures to restore the optimal level regime of the lake were considered.
